I submitted the first draft for NETH3-1 Secrets and Shadows yesterday evening. That was 6 days past my official deadline, but considering my crazy personal schedule I am pleased with how close I came to making that date. I've since already submitted 2 small revisions with a few stat block corrections, a typo here and there, and some formatting changes. Nothing major though.
I tried a couple of new things in this adventure that may end up getting modified so I am expecting to have to make changes on feedback from John and Pieter. Again, nothing major (crossing fingers).
Since this adventure is set to debut at Origins, playtesting will likely be starting up very soon. I have only done limited testing myself so far and will be doing more this coming weekend. Still plenty of time to fix things, iron out rough spots, and polish it. Overall I'm pleased with how this turned out and look forward to how playtesters react to it.
